Description

Carrier device for attaching a laser apparatus to a tube

The present invention relates to a carrier device for attaching a laser apparatus to a tube, consisting of a frame, a receiving arrangement connected to the frame and intended to receive the laser apparatus, and an arrangement of tube attachment connected to the frame and provided with a first tube adapter For the purpose of leveling or marking work in indoor and outdoor construction, laser devices are known which produce laser beams in the form of dots and / or lines . These laser beams are used to carry reference points and / or reference lines on walls, ceilings and / or floors. Among these laser devices, it is necessary to distinguish between the rotating lasers and the lasers point and / or line. Rotating lasers produce a linear laser beam by rotating a laser beam source or beam deflecting optic about an axis of rotation. Dot and / or line lasers produce laser beams through beamforming optics such as cylindrical lenses or prisms. Point and / or line lasers are often self-leveling in a limited angular range. For this purpose, a radiation module is hooked for example to a pendulum arrangement. The radiation arrangement is self-orienting, within the automatic leveling range, in the Earth's gravitational field, regardless of the orientation of the laser apparatus, so that Laser beams are oriented exactly in the horizontal or vertical direction.

To project a laser beam in the form of a dot or line at a given height on a wall, it is necessary to have the laser device at the corresponding height. Various carrier devices are known from the state of the art for attaching a laser apparatus to a tube.

For its laser devices, the applicant offers a wall bracket PMA 71 and a tube adapter PMA 70, which allow, when connected, a fixation on a tube. The PMA wall mount 71 includes a frame, a height-adjustable receiver arrangement connected to the frame for receiving the laser apparatus, and a wall mount arrangement connected to the frame. To attach the laser apparatus to a tube, the PMA tube adapter 70 is connected to the back side of the PMA wall mount 71. The PMA tube adapter 70 includes a fixed contact surface for the tube, two straps and a clamping arrangement for the straps.

In addition, a carrier device is known for attaching a laser apparatus to a tube. The carrier device comprises a frame, a receiving arrangement disposed on top of the frame and connected to the frame, and a carrier device connected to the frame. The carrier device includes horizontal and vertical strap guides, through which a commercially available strap can be passed to secure the carrier device to a tube. With the horizontal belt guide, the carrier device is in contact with the tube from below and, with the vertical strap guide, it is in contact with the tube by its rear side. The disadvantage is that the carrier device is pressed against the tube by a flat surface, which creates a reduced contact area, especially in the presence of cylindrical tubes. In addition, the carrier device with the laser device may tilt.

Conversely, the present invention aims to improve the attachment of a laser apparatus to a tube and to provide the user with a carrier device that allows secure attachment of the carrier device to the tube.

With the carrier device presented in the preamble, this object is achieved, according to the invention, in that the first tube adapter comprises at least two contact surfaces arranged in a V with respect to one another at an angle to apply the tube. The V-shaped contact surfaces of the first tube adapter increase the area of contact between the tube adapter and the tube. While a planar contact surface creates only a linear contact area with cylindrical tubes, a cylindrical tube is applied against the tube adapter by two contact areas if the contact surfaces form a V-shape.

In a preferred embodiment, the tube attachment arrangement comprises a second tube adapter, the second tube adapter having at least two contact surfaces disposed V-shaped relative to each other at an angle to apply the tube. A second V-shaped contact surface tube adapter improves the fastening stability and reduces the risk of tilting of the carrier device associated with the laser apparatus.

In another preferred embodiment, the first tube adapter and / or the second tube adapter are adapted to be adjustable in a vertical direction relative to the frame by means of an adjustment arrangement, the adjustment arrangement comprising particularly preferably, an approximate adjustment arrangement and a fine adjustment arrangement. An adjustment arrangement for adjusting the position of the first and / or second tube adapters in the vertical direction offers the possibility of adapting the carrier device to local data, such as for example short or long tube portions. To increase the stability of the attachment, the distance between the tube adapters should be as large as possible. If the available tube portion is short, the tube adapters can be arranged at a small distance from each other.

In another preferred embodiment, the contact surfaces of the first and / or second tube adapters are adapted to be adaptable. Particularly preferably, the contact surfaces of the first and / or second tube adapters are adapted to be adaptable by means of an adapter arrangement, or the contact surfaces of the first and / or second tube adapters. are shaped as elastic elements. If the contact surfaces, especially the angle between the contact surfaces, are designed to be adjustable, the area of contact between the tube and the tube adapter is enlarged and the security of the attachment is increased.

In another preferred embodiment, the first and / or second tube adapters are disposed on the frame so that they can be exchanged. Exchangeable tube adapters offer the possibility of adapting the carrier device to various tube geometries, for example to rectangular or cylindrical tubes, as well as to various diameters of tubes, respectively to various zones of tube diameters.

Particularly preferably, the receiver arrangement comprises an adjustment arrangement provided with an approximate adjustment arrangement and a fine adjustment arrangement, the receiver arrangement being adjustable in the vertical direction relative to the frame. The adjustment arrangement makes it possible to modify the position of the laser apparatus in the vertical direction, respectively to adjust it with great precision, without having to modify the position of the carrier device on the tube.

Other advantages and advantageous configurations of the subject of the invention will become apparent on reading the description and examining the drawings. Similarly, in accordance with the invention, the features described above and those which will be hereafter can be implemented individually or jointly in any combination. The embodiments shown and described in no way constitute a limiting enumeration and have only an exemplary character to illustrate the invention.

The carrier device 1 according to the inven¬tion, shown in Figure 1 and for attaching a laser device to a tube comprises a U-shaped frame 2, a receiving arrangement 3 connected to the frame 2 to receive the device to laser, and a tube attachment arrangement 4 by means of which the carrier device 1 is attached to a tube.

A laser apparatus is connected to the carrier device 1 by means of the receiver arrangement 3. For this purpose, the receiver arrangement 3 comprises a threaded screw 5 which engages in a corresponding counter-thread of the laser apparatus. The laser apparatus may be disposed on the receiving arrangement 3 directly or via an intercalated adapter. The receiving arrangement 3 is mounted on a front side 6 of the frame 2 and is designed with a possibility of adjustment along the frame 2 by means of a setting arrangement 7. The direction in which the receiving arrangement 3 can be adjusted relative to the frame 2 is called the vertical direction 8. The adjustment arrangement 7 may comprise, for example, an approximate adjustment arrangement and a fine adjustment arrangement for precise positioning.

On the rear side 11 of the frame 2 situated opposite the front side 6, the carrier device 1 comprises the tube-fastening arrangement 4, which makes it possible to fix the laser apparatus to a tube.
